There is a STRICT sound limit of 101 dBA measured 50’ from the line on driver’s right, apex of T12. Attempts to fool the meter or lift will easily be detected by the track’s dedicated sound person (they hate that!). So, please prepare to adjust your muffling system if necessary. This is the same standard that has been in place for years.
